Power TrainSmooth, responsive performance and reliability.
Power Shift TransmissionProvides on-the-go, full-power shifting and inching capability. Direct drive delivers superior fuel efficiency and better “feel” of blade loads, material hardness and ground speed.
Optional Autoshift – Automatic Gear ShiftsThis feature automatically shifts the transmission at optimal points (in gears 3-8) so the operator can focus on the work, improving safety, productivity and ease of operation.
Oil Disk Brakes – Completely Sealed, Adjustment FreeOil-bathed, air actuated and spring-released, located at each tandem wheel to eliminate power train braking loads and to reduce servicing time. The large brake surface area provides dependable braking capability and extended life before rebuild.
Front Axle with Cat Live Spindle DesignCaterpillar sealed spindle keeps the bearings free from contaminants and lubricated in a lightweight oil to reduce owning and operating costs. Two tapered roller bearings support the wheel spindle. The larger tapered roller bearing is outboard where the load is greater, extending bearing life.
Cat® C7 EngineMaximum power and efficiency.Power ManagementThe Cat C7 engine uses ACERT™ Technology to provide electronic control, precision fuel delivery and refined air management, resulting in outstanding performance and lower emissions.
Variable Horse Power (VHP) is standard: base power in gears 1 and 2, 7.5 kW (10 hp) increase in gear 3, and an additional 7.5 kW (10 hp) increase in gears 4 through 8. Customized torque curves increase peak torque for improved lugging performance and responsiveness. The Electronic Throttle Control (ETC) provides easier, more precise and consistent throttle operation.
4
HydraulicsBalanced hydraulics deliver consistent, precise and responsive control.
Balanced Flow, Independent Oil SupplyHydraulic flow is proportioned to ensure all implements operate simultaneously. Independent oil supply prevents cross-contamination and provides proper oil cooling, which means less heat build-up and extended component life.
Implement Control ValvesProvide outstanding operator “feel” and predictable system response for unmatched implement control. To help maintain exact blade settings, lock valves are built into all control valves. Line relief valves are also incorporated into selected control valves to protect the cylinders from over-pressurization.
Load-Sensing Hydraulics (PPPC)A load sensing variable displacement pump and the advanced Proportional Priority Pressure-Compensating (PPPC, or “triple-PC”) hydraulic valves provide superior implement control and better machine performance. PPPC valves have different flow rates for the head and rod ends of the cylinder. Continuously matching hydraulic flow and pressure to power demands creates less heat and reduces power consumption.
Consistent and Predictable MovementThe hydraulic system uses valves that provide PPPC control for precise implement and machine operation. These valves contain spools that are specifically cut for each hydraulic function on the motor grader. They compensate for differences in flow requirements, based on cylinder size and the difference in surface volume between the rod end (blue) and barrel end (red) of the cylinder. The result is predictable, consistent hydraulic speeds whether extending or retracting the cylinder.
5
Structures, DCMEvery component is designed for high strength and optimum durability.
Frame Structure – Provides Consistency and StrengthFront frame is a continuous top and bottom plate construction. Flanged box section design removes welds from high stress areas, improving reliability and durability. The rear frame structure has two box section channels with fully welded differential case for a solid working platform. An integrated bumper ties the rear frame together into a cohesive unit to handle high stress loads.
Drawbar, Circle and Moldboard (DCM)The Y-frame drawbar is constructed of two solid beams for strength, durability, and precise blading control. This design allows the addition of a mid-mount scarifier without compromising blade positioning in extreme reach positions.
The circle stands up to high stress loads. Raised wear surfaces prevent circle teeth wear against the drawbar. The 64 uniformly spaced circle teeth are flame cut and heat induction hardened to resist wear, and the circle is secured to the drawbar by four support shoes for maximum support.
The moldboard provides optimal curvature and large throat clearance that helps move all soil types quickly and efficiently. These features deliver excellent load distribution and minimal material buildup in the circle area while allowing large blade loads to roll freely.
Blade Lift AccumulatorsThis optional feature uses accumulators to help absorb impact loads to the moldboard by allowing vertical blade travel. Blade lift accumulators reduce unnecessary wear and help to avoid unintended machine movement for increased operator safety.
6
Work Tools and AttachmentsAllows expansion of machine versatility, utilization, and performance.
Moldboard OptionsStandard moldboard length is 3.7 m (12 ft), with an optional 4.3 m (14 ft) moldboard available from the factory. Left and right side moldboard extensions (available through the Cat parts system) will increase moldboard surface area and extend reach capability.
Ground Engaging Tools (GET)A wide variety of Cat GET is available from Cat parts system, including cutting edges, and end bits, all designed for maximum service life and productivity.
Rear Ripper/ScarifierThe 120K optional ripper/scarifier is made to penetrate tough material fast and rip thoroughly for easier material movement with the moldboard. The ripper includes three shanks with the ability to add two more if needed. Nine scarifier shanks can also be added for additional versatility.
Front Mounted GroupsA front mounted push plate/ counterweight or front blade can be ordered.
Mid-Mount ScarifierPositioned between the front axle and the circle to break up tough material that the blade can then move, all in a single pass. The V-type scarifier can accommodate up to 11 teeth.
Snow Removal Work ToolsIncludes snow wings, angle blades, and V-plows. Multiple mounting options are available, increasing machine versatility. (Availability may differ by region.)
